long-term safety and tolerability of mesalamine pellets in participants with ulcerative colitis in remission

Conditions: Ulcerative Colitis

Summary: to evaluate the long-term safety and tolerability of encapsulated mesalamine granules (emg) (formerly referred to as mesalamine pellets \[mp\]) in participants with ulcerative colitis currently in remission.

this is a phase 3, multicenter, open-label, treatment extension study evaluating the long-term safety and tolerability of emg given once daily (qd) in participants who successfully participated in a double-blind lead-in study (mpuc3003 \[nct00744016 \] or mpuc3004 \[nct00767728 \]) or new participants who are currently in remission from symptoms of ulcerative colitis.

Eligibility criteria:
